"Poorly handled mental health care"

I went to the CNWL at 190 Vauxhall Bridge Road to access NHS mental health support for the first time. I am a sexual assault victim living with PTSD. After waiting 3 months for the first appointment, I went in for the 1-hour assessment, where I had to go over all details of my trauma for the triage nurse so she could know how to treat. Painful. She referred me to a General Anxiety Disorder treatment 6-week program, where people share with a small group about how they cope with day-to-day stress triggers. After 2 weeks, I communicated to staff that this treatment was WRONG. One staff agreed that I was not receiving the right treatment, but in the end, no action was taken. Of course I felt unsupported and misunderstood. I avoided attending the rest of their classes, but I still needed help... 2 months later, I was feeling very depressed so I reached out to book in actual PTSD treatment and this unnecessarily rude admin told me that I had been de-registered as a patient. He said I would have to re-register, wait a few months for an initial appointment and then re-do my 1-hr assessment, then wait for treatment. I couldn't believe staff for a mental health center would be so rude to staff who like myself, call when they are depressed, or experiencing other symptoms! All in all, seeking counselling from this location was a huge waste of time and caused more negative feelings than positive ones. I did end up receiving PTSD support, but it was from a self-help book which I found at Waterstones.
